Rip Rap and Bulk Aggregates for Erie, IL

Illinois Rock Supply handles gravel and aggregate delivery in Erie, IL, from single loads of CA-6 to full truckloads of rip rap. Whiteside County sits on some of the sandiest ground in this part of the state, so what you pick for a slope or a swale matters.

Start with the calculator on any product page to size the load, then order by the ton or the yard. A dump truck tips it on site.

Materials for Erie Projects

Water moving across a bank or through a swale needs stone that will not wash out. The coarsest material for that work is rip rap, sold by gradation as RR 3 through RR 7.

Use it on bank protection, culvert outlets, pond edges and slope armoring.

Below that size sits #4 Crushed Stone, a 1 1/2 inch clean stone.

It works for construction entrances, heavy drainage and trench bottoms.

For bedding and drainage trenches, Illinois contractors specify CA-7 and CA-11. CA-7 is washed clean stone with no fines, for bedding under pipe, French drains and concrete flatwork.

3/4" Crushed Stone is the CA-11 size sold alongside it.

Where a compacted base is the goal, CA-6 is the Illinois base material: dense graded crushed limestone with the fines left in. It goes under driveways, parking pads, shed and garage bases and trench backfill.

At the fine end, Lime Screenings bed pavers and flagstone and backfill around pipe. Washed Sand, which Illinois yards call torpedo sand, is the coarse washed sand for concrete and leveling.

Ground and Conditions in Erie

The working season here runs from the spring thaw into late fall, a little shorter than downstate. Frozen ground stops compaction in winter, so timing a delivery matters.

Across the Northern Illinois till plains and Rock River country, the ground is Wisconsin Episode till and loamy prairie soils over dolomite. Sand and gravel of the Green River Lowland break that up.

Tight till and a high water table sit on the flat ground, while sand plains drain almost too fast.

Snowmelt and spring rain on frozen ground push water across the surface. That is where gully and sheet erosion show up on steeper till slopes, and wind moves bare sand.

Frost action is heavy in unbound base and shallow footings here. Frost depth is about 42 inches across the northern counties, and the local building department sets the figure that applies to your footing.
